Awesome fuel!!! Runs cool and has great lubrication. You dont even need after run oil with this fuel. It keeps you engine super clean,rust free and a nice coating after using this fuel is on all the internals. Best fuel I have ever used. Also got better mileage with this fuel and about 15 degree lower engine temps. Than byrons or nitrotane. -//- Best fuel ever!! does not rust inside of engine like nitrotane. and runs super cool!!!! -//- This fuel is top notch! I have ben in the hobby a long time and tried a lot of fuel and this fuel is great!! actually got 11 gallons out of my werks B7 with this fuel with my old fuel I got 8 gallons out of my previous B7. Runs cool, killer power and makes engine last!!!
